Theres smut but its in season two im pretty sure.
Their relationship moves slow but also fast at the same time if that makes any sense?
Whipped up a quick list of some of the ones I remember. So far most of these have like.. zero smut and are fairly short so idk if that's really your speed.
Still building this out but hopefully you'll find something here idk
